yes, the numbers make a differance. There are at least 5 different part numbers for the front and 5 for the rear. Not all rubis have the same springs as not all 2 doors have the same either. You can probably put 2 rubis with exactly the same options side by side and they wouldn't have the same springs in them!!!! I too am interested. The fronts shoud be 52126315 thru 52126319, rears 68004456 thru 68004460.
